FFOS: adding a camera photo crashes app

[gesa]

OS: FFOS b2g 2.0.0.0-prerelease
Browser: N/A
Screenshot: N/A

Repro Steps:

1. In the inline editor for a photo block, tap the pencil
2. Choose "Camera"
3. Take photo, tap "select"

Expected: Edited photo in app is replaced with camera photo, return to app
Actual: Inline editor view returns to screen with original photo still in the block. after a few seconds, app crashes.

note: the new photo is being saved before the crash. Upon relaunching the app, the new photo has taken the place of the old one

@gesa can you reproduce this using this build of FFOS (2.2) on the Flame? I cannot.

I'm able to reproduce on 2.0.0-prerelease but only by taking lots of photos sequentially. After some period of time, the amount of memory used by both the app and the camera application hits some device-specific threshold and the OS will kill the webmaker process in the background while the Camera app is open. This is similar to how inter-app communication works (or rather, doesn't) in Tarako.

Walked through this with @gesa on Vidyo. Looks like this is resolved in Firefox OS 2.1/2.2
